Create Unity Parameter Asset? Uhhh i think?

So this is silly. I started creating a game 5 years ago. I create an *.asset file, and i use it as universal parameters. How can i create another one but have it point to a different script?

Its marked as a script able object. And i cannot for the life of me figure out how to add another one to my game. 154938-capture1.png.
